Abstract

Seed production occupies a special place in the system of activities aimed at growing a high and sustainable yield from grain crops. One of the main tasks of seed production is to increase the high-quality seeds of newly created varieties included in the State Register and recommended for production, and to adequately satisfy the demand for production. In order to carry out seed breeding work properly, it is necessary to have a good knowledge of the biological and variability characteristics of the cultivated varieties. In the absence of selection, both self-pollinated and cross-pollinated cultivars are subject to biological and accidental contamination. Therefore, it is highly effective to carry out individual selection works in the field of seed breeding with a good knowledge of the valuable economic characteristics and characteristics of the varieties.
